The "Altenberg Workshops in Theoretical Biology" address key questions of biological theories. Each workshop is organized by leading experts of a certain field who invite a group of international specialists to the KLI. The Altenberg Workshops aim to make conceptual progress and to generate initiatives of a distinctly interdisciplinary nature.

Topic description / abstract:
“Life History Theory” (LHT) is an evolutionary concept derived from Behavioral ecology that aims to explore differences between species with regard to a trade-off between reproduction and somatic growth. Accordingly, species differ not just in body size, number of offspring, and lifespan – in fact, these differences co-vary in quite peculiar ways. Indeed, differences in Life History Strategies (LHS) explain between-species variation concerning age at sexual maturation, growth rate, parental investment, mortality rate, immune function, mutation load, and in efficiency of body repair mechanisms.
In the last decades, evolutionary psychology has adopted LHT to suggest that differences in LHS not only exist between species, but among members of the same species, including humans. One of the landmark articles in this regard posited that in human families, harsh environmental contingencies during early developmental stages, including contextual factors such as family discord, poverty etc. may predispose parents to adopt an insensitive, rejecting or inconsistent rearing style, which could impact the child’s view of the world as insecure, thus promoting mistrustful or opportunistic interpersonal behavior. Together, following these lines would increase the likelihood for a “faster” LHS, compared to more secure environmental conditions. However, the adoption of LHT by evolutionary psychology to explain individual differences between members of the same species has raised methodological concerns among evolutionary biologists.
A crucial question for psychiatry is whether the concept of LHT, or its evolutionary psychological derivate, can be meaningfully applied to psychopathological conditions. In the present talk, I will argue that theoretical frameworks, based on evolution by natural and sexual selection, can improve our understanding of the nature of psychopathological conditions, in spite of limitations that are largely associated with disparities between psychological and biological development. LHT, for example, can fruitfully add to insights from attachment theory, which to date is the only evolution-based theory that has prevailed in psychiatry. LHT can also form the basis for empirically testable predictions about comorbidity, and clustering of symptoms, both psychiatric and somatic. If confirmed, LHT may be potentially useful in the domain of preventive medicine, which is highly relevant in light of reduced life expectancy of people with mental disorders.
Biographical note:
Martin Brüne was born in Dortmund, Germany, in 1962. He graduated in medicine at the University of Münster in 1988. He completed his neurology training in 1993, and his psychiatry training in 1995. His subsequent training included a Visiting Research Scientist fellowship at the Centre for the Mind, a joint venture of the Australian National University and University of Sydney. He is currently Professor of Psychiatry and Head of the Division of Social Neuropsychiatry and Evolutionary Medicine at the LWL University-Hospital, Ruhr-University Bochum, Germany.
Dr. Brüne has authored more than 300 articles and book chapters. He has also authored the “Textbook of Evolutionary Psychiatry and Psychosomatic Medicine: The Origins of Psychopathology” (2nd edn. Oxford University Press, 2016). He served as the Editor (together with Prof. Wulf Schiefenhövel) of “The Oxford Handbook of Evolutionary Medicine” (Oxford University Press, 2019), and (together with Profs. Nico Diederichs, Christopher Goetz and Katrin Amunts) of “Evolutionary Roots of Human Brain Diseases” (Oxford University Press, to be released in autumn 2024).
His current clinically oriented research projects include the analysis of social cognition in psychosis and in personality disorders, the association of social cognition with social functioning and nonverbal behaviour, the behavioural performance of psychiatric populations in evolutionary game-theoretical scenarios, the effect of oxytocin on social perception and cognition in psychiatric disorders, nonverbal interaction in therapeutic settings, genetics and epigenetics involved in social interaction, and psychopathology in nonhuman animals.
Dr. Brüne’s research approach is grounded in evolutionary theory, that is, how and why cognition, emotion and behaviour in psychiatric conditions relate to adaptive function of psychological traits.
Dr Brüne is a member of several psychiatric and neuroscientific societies (Deutsche Gesellschaft für Psychiatrie, Psychotherapie und Nervenheilkunde (DGPPN), International Society for Human Ethology (ISHE), Gesellschaft für Anthropologie (GfA), and the International Graduate School of Neuroscience (IGSN), Ruhr-University Bochum.
